Whoopsy, I'm sorry for the mix-up! I was probably (trying to)
multi-task too much :)

I've tested David's patch (applied on top of plain kernel v3.6), and
confirm that this fixes the issue. Auto-mute when plugging in
headphones still works as expected too. Thank you for the quick fix!
Will you be closing the bug at the kernel's bug-tracker once the fix
is upstream (or should I do it now)?
